Hello, Looking for guidence. Went to lunch yesterday. When I returned I shut off the car (90 Maui Blue) and the defroster kept running. Wouldn't stop, so I tried to find fuse to remove...no luck. Hour later, defroster still running. Went to drive it home and 20 minutes into drive (air working well) blower and defroster both stopped running. Pushing buttons on climate control cause expected display but no blower ever comes on. Pushing controls for air causes compressor noise under hood but no blow. Any suggestions...hot outside. Fred
